A range of ruthenium‐arene compounds with chloride, bromide or iodide ligands were prepared and tested as catalysts for the homogeneous redox neutral alkylation of tert ‐butylamine with phenethyl alcohol, and compared to the previously reported catalyst [RuCl 2 ( p ‐cymene)] 2 , in the presence of the diphosphine 1,1′‐bis(diphenylphosphino)ferrocene (dppf). The best catalytic activities were obtained with ruthenium iodide compounds. The formation of either [RuX( p ‐cymene)(dppf)][X] or [(RuX 2 ( p ‐cymene)) 2 (dppf)] (X = halide) under the catalytic conditions employed was investigated.
